I think that numbers are different in different sources, because once there are only people deported in 39-41, in other sources those deported in 39-53, also sometimes they include only ethnic Poles, sometimes everyone who was a Polish citizen before 39.===
I think it could be former polish later soviet citizens from West Ukraine. BUT they didn't die as it claimed. After 1956 when Khruschev came to power most of them returned back. Not all. SO I saw some western ukranians in Sibiria.
Soviet Union didn't exiled non soviet citizens.
I never saw and heard germans from East Germany, poles, hungarians, chekhs.
BUT tell me honestly Greg after all we know now to say as m_68 that "700 thousand poles were kiled by russians and other 2 mlns sent to Sibiria" is distortion?
